A customer information management system which enables integration of data across lines of business that classify data using distinct formats. In the system, a plurality of lines of business are in communication with one another and with a customer server. A customer information model produces a common classification format used by the customer server. Adapters at each line of business translate information between the format used by the customer server and the format used by the respective line of business. In use, the customer server may glean information from all of the lines of business and produce detailed data stores about customers. A first line of business may also obtain information from a second line of business by making a request through the customer server.
